I should have noted, the client for me was the band, and they were in full agreement with me. There was much more I didn't discuss in my initial post - a lot of negativity by the venue and a complete lack of cooperation during load in and setup. This was all before I said anything.
I certainly will think twice about doing these shows. I've done a bunch over the years without a hitch - everyone happy. I also do not need the work, and take only gigs I want to do (lounge). And yes, I showed up with too much rig for the gig.
